Asexual Awareness Week, also known as Ace Week, is an annual international campaign held during the last full week of October. Its goal is to educate the public about the diversity of asexual, aromantic, demisexual, and grey-asexual experiences and to provide a voice for the asexual community. It aims to raise awareness of the asexual umbrella and to correct misconceptions about asexuality.

Ace Week focuses on the asexual spectrum, which includes various identities like demisexual (attracted after an emotional bond) and grey-asexual (attraction is rare or limited).
